Trialkylacetic acids

2-dimethylpropaaoic acid (also, neopentanoic acid, pivaUc acid). For higher members ia the series, the products are typically mixtures of isomers, resulting from the use of mixed isomer feedstocks and the chemical rearrangements that occur ia the manufactuting process. [Pg.102]

Trialkylacetic acids have been produced commercially siace the early 1960s, ia the United States by Exxon and ia Europe by Shell, and have been marketed as neo acids (Exxon) or as Versatic Acids (Shell). The principal commercial products are the acid and the C q acid (neodecanoic acid, or Versatic 10), although smaller quantities of other carbon numbers, such as C, C, and C, are also produced. [Pg.102]

The trialkylacetic acids have a number of uses ia areas such as polymers, pharmaceuticals, agricultural chemicals, cosmetics, and metal-working fluids. Commercially important derivatives of these acids iaclude acid chlorides, peroxyesters, metal salts, vinyl esters, and glycidyl esters. [Pg.102]

Chemical Properties. Neopentanoic acid [75-98-9] undergoes reactions typical of carboxyUc acids. Reactions often proceed less readily than with straight-chain acids because of the steric hindrance around the carbonyl group. However, this steric hindrance at the a-carbon results ia derivatives that are typically more resistant to hydrolysis and oxidation. [Pg.102]

Acid Chloride Formation. Neopentanoic acid can be converted to neopentanoyl chloride [3282-30-2] by reaction with thionyl chloride (2), phosgene (3), phosphoms pentachloride, phosphoms trichloride, or by the reaction with henzotrichloride ia the presence of Eriedel-Crafts catalysts (4). A laboratory procedure usiag tetramethyl-a-halogenoenamines at room temperature has also been reported (5). [Pg.102]
